Visuals are a large part of spec identity, which is sometimes called look and feel. The same could be said of Icicles, they could have just as easily went the easy path and made a flat +damage mastery but instead went with something visually cool; functionally they're just targeted Ignite. You could potentially prune a lot of spells by rolling their damage into others, but that doesn't usually make for compelling gameplay, and makes any given spec less interesting from a visual standpoint.
